Fire stopping for businesses in Great Canfield

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Fire stopping for commercial buildings in Great Canfield

For main contractors, our fire stopping package slots in after the M&E trades have finished in an area. To price a package, give us a call on 01277 525 020 or send photos by email with the schedule or marked-up drawings. Tell us what records you need and we will confirm with the quote. If you’re dealing with old intumescent sealant that has split away and openings found when ceilings come down for a refit, we can help, on pipe penetrations, linear gaps at wall heads and service gaps in risers alike. Whoever orders the work in Great Canfield, the brief is usually the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Smaller places such as Great Canfield still have buildings with fire-resisting walls and floors: schools, halls, care homes and commercial conversions. Any service penetration through those walls should be closed with the specified product, set out as its test evidence shows.

We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

What happens if it’s left?

An unsealed opening affects more than fire safety: they also carry noise, draughts and smells between rooms. Sealing them to the specified detail deals with the fire risk first, and the other benefits follow. Halls, stores and units around places like Great Canfield may not be checked every day, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.

We don’t publish prices, since every building and every scope is different. For a fixed figure, call for a quote.

Read what affects the cost or how we’re accredited.

How the quote is worked out

To price the job, we consider:

  • The size and state of each joint
  • How much there is to seal
  • The site’s rules and procedures
  • How accessible the joints are

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

What we need to price the job

The more we know, the firmer the quote. When you get in touch, include:

  • The postcode of the building
  • Clear photos of the problem areas
  • Any specification or named product
  • How the joints are reached, and at what height

Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we will fill any gaps with a visit.

Questions about Great Canfield

Is Great Canfield too small for you to travel to?

Not at all. Great Canfield is within our area. Our area covers London and the South East counties. Good photographs up front let us bring everything on the first visit.

Do you cover business parks and estates near Great Canfield, such as Blue Gates Industrial Park?

Yes, sites like Blue Gates Industrial Park are within our area, along with the rest of Great Canfield. Photos and a short description are enough for a first look.

How do we ask for a quote?

You can use the quote form on this site; alternatively, call 01277 525 020 or use the quote form. Photos, drawings or a joint schedule help us quote quickly.

Can you quote from photos?

Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit before quoting.

Is your workmanship covered by a guarantee?

Yes. The 12-month guarantee covers our preparation and application, but not damage, misuse or other trades’ work.

Is the BS 476 change in 2029 relevant to fire stopping?

For buildings in England, Approved Document B removes BS 476 references from 2 September 2029. Classification to BS EN 13501-2 becomes the expected evidence. Scotland follows its own Technical Handbook.

How long before the joints can be used?

Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.

When to call us in Great Canfield

Plenty of openings were simply never closed, often hidden above suspended ceilings or behind boxing. Inspections, refurbishments and ceiling access normally bring them to light.

If one of these sounds familiar, it’s time for a closer look:

  • Fire-stopping items raised at inspection or handover
  • Fire sealant pulled out of the opening
  • Hidden openings found during inspections
  • Expanding foam used as fire stopping

Where a unit on an estate such as Blue Gates Industrial Park, 2.4 miles north of Great Canfield, has fire-resisting walls between offices and warehouse, any new service through them should be sealed to the tested detail.

What to look for in a quote

  • Proof of insurance
  • How joint depth will be controlled
  • Their pre-qualification and accreditations
  • What the guarantee covers, and for how long

Choosing a commercial sealant contractor

Work for main contractors and building owners

Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.

For main contractors, we work as the sealant subcontractor. We work to your programme, your specification and your site rules.

Doing it in-house

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.

On site: what to expect

Site rules come first: signing in, inductions and any permit to work. With the paperwork done, we take the joints in the sequence agreed with you. For work around Great Canfield, we aim to finish in one visit, so photographs and measurements up front really help. That way the right products come on the day.

  1. We ask for the product and detail your designer has specified.
  2. We sort the openings by the detail each one needs.
  3. Old or wrong materials are cut out.
  4. Where the detail needs backing, it goes in at the stated depth.
  5. Fire-rated or intumescent sealant goes in around the services and is tooled off.
  6. We walk the completed areas with you and confirm the records agreed at quote stage.

Preparing the site

  • Tell us what induction or permit system the site runs
  • Confirm the product named in the specification
  • Point out parking and an unloading spot

Ask for a quote

Send us photographs, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.

Service penetrations in Great Canfield buildings

Great Canfield is about 29 miles from central London. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls, and the gaps need sealing with the specified product. In England, Approved Document B covers fire stopping of openings and penetrations. References to the older BS 476 classes are being removed from it from 2 September 2029, after which the European classification, BS EN 13501-2, is the route, subject to transitional arrangements. What we install is set by the specification, and it goes in to the tested detail.

Halls and meeting rooms at places like Parish Church of St Mary sometimes gain new services, and any compartment wall crossed needs the specified seal.

Great Canfield is about 3 miles south-west of Great Dunmow, in Essex. Across the CM6 postcode area, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. Our Essex coverage takes in 644 places. Sites around London have their own page, about 29 miles away.

Nearby places we also cover include High Roding (1 mile east), Roundbush Green (2 miles south), Keeres Green (2 miles south), High Easter (2 miles south-east) and Stagden Cross (3 miles south-east) for service penetrations. Nearby towns on our patch include Chelmsford (10 miles south-east), Braintree (11 miles east), Harlow (10 miles south-west), Brentwood (14 miles south), Billericay (15 miles south) and Witham (14 miles east).
